adapted for use when the ends oi a belt are to be joined, though it is useful for other purposes. It consists in means attach: able to the belt ends and means for pulling the belt ends together and holding them is fixedly in position during the joining operation. 1

My invention will be understood with ref-= erence to the drawings in which it is shown in its preferred form.

Figure l is a plan of my device.

Fig. 2 is a front elevation of one of. the belt clam 1' v Fig. 3 IS a longitudinal section of the clamp, and

Fig. d is a vertical section on line dd of Fig. 2.

Fig. 5 is a vertical section on the line 5-5 of Fig. 1.

.1, 1 are the belt clamps each adapted to be attached to'an end of abelt. I

The clamp comprises a body 2 having lugs 3 between which is hinged the swinging member 4. This swin 'ng member is broadened and forked at its free end as at 5.

The body membend is recessed as at 6 its release being preferabl provided with a lining 7. Within the inmg is hinged the clamping member by the pin 8. "The clamping member comprises a screw 9 enlarged at its hinged end and perforated to receive the hinge pin 8, this the body 2 and lining At its upper end the screw 9 carries a-washer 10 and a retainin'g nut 11 which is preferably provided with a handle 12 bywhich the nut may be easily manipulated. The .body 2 is also provided with a hole through which passes the threaded shank 13 of a holder 15, 16, 130 be a nut which screws onto the shank 13 an clamps together the holder and the body 2. y

' The clam s are attached to the ends of the belt. The holder 15 has pivotally connected to its outer endarmslfl and18. The

belt ends in close passing also through outer end of arm 17 is pivotally connected to one of the lovers 19, the arm 18 being similarly connected to the other lever 20, j

one end of each of the levers 19, 20 being pivotally connected to the outer end of the holder 16. A slotted-ad'usting arm 21 having a hub 211 is pivote to the arm 17 and reaches over the arm 18 and may be clamped thereto b a screw 22 which projects up through t earm 18 and the slot in the arm '21. A handled nut 23 screws onto the screw,

22 so that it may bind the as 18 and 21 in any. desired position.

My device is operated as follows: The

belt clam are opened as in Fl. 3 and an end 0 the belt is placed in sec clamp between the swinging member and the body, after which the swinging member is closed down against the belt and the clamping member is swun up so that the washer 10 r on the for 'of the swinging memmr (see Fig. 2). Th outer ends ofthe levers 19 and 20 are then separated (the nut 23 being first loosened) as far as possible so asto draw up the clamp, ulling the belt ends to other as far as possle, and the nut 23 is t en screwed down so that the adjusting arm is firmly clamped against the arm 18, thus holding the arms 17 and18 in extended positionyand the clamps and proximity so that the ends of the belt are cc to be worked upon without strain, the clamps being placed as. far from the extreme ends of the belt ascircumstances require and allow.

When the work on the belt ends is finished, for example, when they are laced 'or otherwise connected together, the adjusting arm 21 is released, and the belt is released from the clamps.

It will be seen that by means of a devlce v embodying my invention the two ends of 'a belt may be adjusted a'bout pulleys and the ends laced or otherwise attached together so that this tension is maintamed after the device is removed. It. will also be seen that my invention may be otherwise embodied. By the word clamlp I.

dipgmean to include any means for he the belt ends.

WhatI claim as my invention is 13A device of the kind described imi i i g;v

two clamping means, a pair of levers pivot 1y connected one of'said clamping means,

and links connecting said levers to the other clamping means, whereby a movement of said levers will cause said clamps to approech.

2. A device of the kind described having two clamping means, a, pair of levers pivotally connected to one of said clamping means,
